Why is it important to round numbers?
It is important to round numbers for simplicity's sake. Rounding numbers makes them "friendly" and much easier to work with. "Friendly" numbers allow people to utilize the simplest multiplication, addition, subtraction, division, and/or counting patterns to make calculations and/or estimations. Calculating the cost of 18 items @ $9.65 using mental math is far more complex for most than rounding that to 18 items at $10 to get a rough number. There are obviously times that an exact number is necessary, but even in those instances, rounding is a good tool for checking the validity of your answer by giving you a ballpark figure.
